FLORA OF ANN ARBOR AND VICINITY. 



In accordance with the directions of the Association, the 

 Committee on the Flora of this vicinity have made out a report. 

 The report includes the Phaenogams and three orders of Vascular 

 Cryptogams. 



The Committee were limited to a circle having a radius of 

 four miles, Ann Arbor being the center. Within these limits we 

 have represented one hundred and one (101) orders, three hun- 

 dred and seventy-eight (3 7-8) genera, and eight hundred and 

 forty-eight (848) species. 



Dr. Gray, in his Botany of the Northern States, gives one 

 hundred and thirty orders ; as already stated, we have one hun- 

 dred and one represented, leaving only twenty-nine of which we 

 have no representatives in this small tract of country. This 

 shows the richness in variety, at least, of this vicinity. 



We have appended lists of exterminated, rare and local, 

 and introduced plants. Of exterminated plants there are four- 

 teen (14) species. This number includes Nyssa multiflora or 

 Pepperidge tree, the wood of which is very hard, and was for- 

 merly used for beetles and wedges ; also Dirca palustris, which 

 was used by the Indians for thongs. 



Of rare and local plants there are thirty-two (32) species, 

 this number including Viola rostrata, which is called one of the 

 rare violets. With us it is one of the most common. In this 

 list of rare and local plants, there is one, viz. : Aplectrum hya- 

 male, commonly called putty root, and also known as Adam and 

 Eve, which will soon be added to the number of exterminated
